An Overview of Technical and Economical Feasibility of Retrofitted MHD Power Plants from the Perspective of Bangladesh

摘要

A retrofitted MHD power plant is particularly attractive for older plants that have to be reconditioned since these may increase the generating capacity of the existing plants and at the same time, reduce the emission of pollutants and cooling water requirements. This would extend the life of an existing power plant and improve its environmental intrusion. The purpose of the paper is to study the feasibility of retrofitted MHD power plants if would have been adopted in the existing plants of Bangladesh. Many of the thermal power plants commissioned in Bangladesh are 30-40 years old. Retrofitted MHD power plants may be an option to increase the performance of these plants as there remains ? large coal reserve in Bangladesh where the gas reserve is approaching towards its end. The feasibility studies of MHD plants demonstrated that combined cycles using both open and closed cycle MHD processes should be economically competitive. The technology has reached the stage where the feasibility of retrofit demonstration plant is considered by several countries including USA, Russia, China, Japan, India and Australia. A developing country like Bangladesh may step forward to adopt the technology to handle its recent energy' crisis.
